Data analytics is not about the the tools you master but about the people you influence. I see many debates around the best tools such as: - Excel vs SQL - Python vs R - Tableau vs PowerBI - ChatGPT vs no ChatGPT The truth is that business doesn't care about how you come up with your insights. All business cares about is: - the story line - how well they can understand it - your communication style - the overall feeling after a presentation These make the difference in being perceived as a great data analyst... not the tools you may or may not master 😅

How to get job as python fresher? 1. Get Your Python Fundamentals Strong You should have a clear understanding of Python syntax, statements, variables & operators, control structures, functions & modules, OOP concepts, exception handling, and various other concepts before going out for a Python interview. 2. Learn Python Frameworks As a beginner, you’re recommended to start with Django as it is considered the standard framework for Python by many developers. An adequate amount of experience with frameworks will not only help you to dive deeper into the Python world but will also help you to stand out among other Python freshers. 3. Build Some Relevant Projects You can start it by building several minor projects such as Number guessing game, Hangman Game, Website Blocker, and many others. Also, you can opt to build few advanced-level projects once you’ll learn several Python web frameworks and other trending technologies. @crackingthecodinginterview 4. Get Exposure to Trending Technologies Using Python. Python is being used with almost every latest tech trend whether it be Artificial Intelligence, Internet of Things (IOT), Cloud Computing, or any other. And getting exposure to these upcoming technologies using Python will not only make you industry-ready but will also give you an edge over others during a career opportunity. 5. Do an Internship & Grow Your Network. You need to connect with those professionals who are already working in the same industry in which you are aspiring to get into such as Data Science, Machine learning, Web Development, etc. Python Interview Q&A: https://topmate.io/coding/898340 Like for more ❤️ ENJOY LEARNING 👍👍
